In this report, an optimal control of the closed circuit grinding system in a cement process is discussed. Generally, it is known that there is an optimum circulating load at which the efficiency of comminution is maximum. However, as control variables, the amount of electricity consumption of a bucket elevator is used instead of the circulating load for measuring reasons in this experiment. As the control system, a combination control system of fuzzy control and LQI control is constructed. The inside situation of a mill is inferred by fuzzy reasoning and the reference value of the sound level of the mill is determined on the basis of reasoning results. Then the supply of clinker to the mill is adjusted by LQI control such that the mill sound level follows to reference level. As a result, it is found that the proposed control system is very applicable and good control performance is obtained.
